Malvern Instruments latest INFORM white paper - ‘The benefits of real-time analysis for process development’ - presents the case for investing in real-time process measurement at the pilot studies stage, and is now available for free download from the company’s website: www.malvern.com/realtime. While much effort is expended in optimizing commercially operating plant, getting the process ‘right first time’ can be far more efficient. Real-time analysis of process parameters provides substantial support during development, streamlining and accelerating the evolution of successful process designs. Taking on-line particle size analysis as an example, this paper considers the rationale for investing in real-time measurement for pilot-scale work. Case studies are used to illustrate the various ways in which on-line systems promote efficient process development, easing the transition into profitable manufacturing.
